NASA's Hot 100 Technologies: Power Generation & Storage

Model-Based Prognostics For Batteries Effective Battery Health Monitoring (BHM) technologies are needed to ensure that battery operation is optimal and, if not, that it stays within design limits. BHM technologies protect the asset’s batteries from degradation due to non-optimal usage, and ensure viable levels of system availability, reliability, and sustainability in the presence of degraded batteries.

Technique Generates Electricity from Mechanical Vibrations

Research scientists at VTT Technical Research Centre of Finland have demonstrated a new technique for generating electrical energy. The method can be used in harvesting energy from mechanical vibrations of the environment and converting it into electricity. Energy harvesters are needed in wireless self-powered sensors and medical implants, where they could ultimately replace batteries. The technology could be introduced on an industrial scale within three to six years.

Solar Material Converts 90 Percent of Captured Light into Heat

A multidisciplinary engineering team at the University of California, San Diego developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in spite of exposure to air and humidity. “We wanted to create a material that absorbs sunlight that doesn’t let any of it escape. We want the black hole of sunlight,” said Sungho Jin, a professor in the department of Mechanical and Aerospace Engineering at UC San Diego Jacobs School of Engineering. Jin, along with professor Zhaowei Liu of the department of Electrical and Computer Engineering, and Mechanical Engineering professor Renkun Chen, developed the Silicon boride-coated nanoshell material. The novel material features a “multiscale” surface created by using particles of many sizes ranging from 10 nanometers to 10 micrometers. The multiscale structures can trap and absorb light which contributes to the material’s high efficiency when operated at higher temperatures.SourceAlso: Read more Materials tech briefs.

2-in-1 Motor Increases Range of Electric Cars

Scientists from Nanyang Technological University (NTU) and German Aerospace Centre (DLR) have invented a 2-in-1 electric motor that increases the range of electric vehicles. The engine integrates the traditional electric motor with the air-conditioning compressor, typically two separate units. This novel, space-saving design allows the use of bigger batteries, which can increase the range of electric vehicles by an additional 15 to 20 percent.

Improved Fuel Cells Could Replace Phone and Laptop Batteries

Fuel cells could replace batteries in mobile phones and laptop computers, and the UPV/EHU-University of the Basque Country is looking at ways of enhancing their efficiency. Researchers are designing new ways of obtaining energy in a cleaner, safer, and more affordable way. Fuel cells are totally appropriate systems for substituting the batteries of such devices. They turn the energy resulting from the combining of hydrogen and oxygen into electrical power, with water vapor being the only waste product.

Ultra-Thin 3D Display Promises Greater Energy Efficiency

An ultra-thin LCD screen, developed by a group of researchers from the Hong Kong University of Science and Technology, holds three-dimensional images without a power source, making the display technology a compact, energy-efficient way to display visual information.In a traditional LCD, liquid crystal molecules are sandwiched between polarized glass plates. Electrodes pass current through the apparatus, influencing the orientation of the liquid crystals inside and manipulating the way they interact with the polarized light. The new displays ditch the electrodes, simultaneously making the screen thinner and decreasing its energy requirements. Once an image is uploaded to the screen via a flash of light, no power is required to keep it there. Because these so-called bi-stable displays draw power only when the image is changed, they are particularly advantageous in applications where a screen displays a static image for most of the time, such as e-book readers or battery status monitors for electronic devices. “Because the proposed LCD does not have any driving electronics, the fabrication is extremely simple. The bi-stable feature provides a low power consumption display that can store an image for several years,” said researcher Abhishek Srivastava.The researchers, however, went further than creating a simple LCD display; they engineered their screen to display images in 3D.
